If portfolioαfirst-order stochastically dominates portfolioβthen\(F_{k} \left( {\varvec{\alpha}} \right) \le F_{k} \left( {\varvec{\beta}} \right)\)for all\(x_{k} \in X\). Expected return (3) of portfolioαcan be then written as $$ \begin{aligned} ER\left( {\varvec...
No representation is being made that any client account will or is likely to achieve profits or losses tied to a security in the security model forecasts. In fact, there could be significant differences between these forecasted performance results and the actual results realized. Forecasted ...

We now regard the schedulers\(\mathfrak {S}_n\)for\(n =1,2,\ldots \)that choose\(\beta \)for the firstnvisits of\(s_2\)and action\(\alpha \)for the\((n{+}1)\)-st visit of\(s_2\). Then: $$ \mathbb {CE}^{\mathfrak {S}_n} = \frac{\frac{1}{2} \cdot \ma...
Verifiability and predictive value are two ingredients of faithful representation. a. True b. False The efficient-markets hypothesis states that the return of a security is based on its risk. a. True b. False A favorable variance indicates tha...

Ah so since Godot 4.0, the string representation of bools has changed? This kind of bug could quickly be avoided by replacing the hard coded "True" with the similar conversion of the Godot bool true to string then, e.g. another output of getGlobal? Member akien-mga commented Nov 17, ...
C. Expected value D. Simulation Failure modes and effects analysis (FMEA): It is the process that helps to understand the reason and the possible impacts of the failure modes. After analysing the process, it also helps to take actions ...
Representation pertains to the embodiment of the prototype, which could either be in the form of paper or mobile, or HTML and desktop. Precision refers to the extent to which the prototype is faithful, detailed, refined, and lifelike.
For this non-parametric model, we assume that the distribution of past returns is a perfect representation of the expected future returns. The advantage is that we do not impose any assumptions about the underlying probability distributions. Historical simulation is heavily sensitive to the length of...
